Specifications include, but are not limited to: The Seattle Transit Master Plan has designated Aurora Avenue between the north city limits and Downtown as a Frequent Transit Network priority bus corridor. RapidRide E Line is scheduled to begin service on Aurora Avenue in September 2013, when the E Line replaces Route 358. To accommodate the the E Line, the project will include significant roadway and signal operations improvements for transit. The purpose of this study is to prepare an assessment of proposed transit speed and reliability improvements, including BAT lanes, and their impacts on transit, general purpose traffic, parking and pedestrians throughout the corridor. Options for implementing BAT lanes on Aurora Avenue range from peak period, peak direction to all day, seven days a week. This study will conduct a thorough assessment of up to four different options and analyze the impacts of each option compared to existing conditions of the corridor, with an option to fully design the transit priority. Project Limits: Aurora Avenue between N. 145th Street and Bridge Way North Task 1: Project Management and Administration The consultant will be responsible for documenting and reporting all communications (coordination meetings, phone conferences, electronic correspondences, etc.) to the SDOT project manager. The consultant shall provide project status and budget updates as requested by the SDOT project manager. Any changes to budget or scope of work proposed by the consultant must be reviewed and approved by written or electronic notice by the SDOT project manager. The estimated cost for these tasks ranges between $80,000 100,000. Task 1 Deliverables: - Project status, meeting summaries and budget updates Task 2: Update Existing Synchro Model The consultant will update AM, midday, and PM peak period Synchro models provided by SDOT for the Aurora Avenue corridor between N. 145th Street and Bridge Way. The consultant will also coordinate with SDOT and verify and obtain the current signal timings for each intersection on Aurora Avenue and up to two side street intersections. Task 2 Deliverables: - Updated existing AM, midday, and PM Synchro Models Task 3: Conduct a Multi-Modal Analysis of Aurora Avenue using VISSIM The consultant will evaluate and assess the effect of improving capacity and efficiency of movement on Aurora Avenue through modification or removal of on-street parking on Aurora Avenue and installation of a Business Access and Transit lane. Four different traffic scenarios will be simulated for comparison with existing conditions, including: - Peak period, peak direction BAT lanes - Peak period BAT lanes in both directions - Peak period and midday BAT lanes in both directions - 24/7 BAT lanes in both directions
